To all whom it may concern.

Be it known that 1, HERMAN A. Hun-ran, a citizen of the United States,residing at Charleroi, in the county of Washington and State ofPennsylvania, have invented certain new and useful Improvements in Take-Out Mechanism for Glass-Machines, of which the following isaspecification.

This invention relates in general to takeout mechanism for glassmachines and particularly to mechanism for the removal of the blow pipesin glass blowing machines. It has for its primary objects; the provisionof'an improved mechanism for taln'ng out articles from a glass machineand for pre-' serving the shape of the \articles until the glass is set;the provision of an improved from the glass machine during the operationof the same; and the provision in a take-out mechanism of the characterspecified of means for supporting the glass articles after removal fromthe blowing machine. These together with such other ob};

jects as may hereinafter appear or are incident to my invention llattain by means of a construction which 1 have illustrated in preferredform in the accompanying drawings wherein: y

Figure 1 is a side elevation of a rotary glass blowing machine of theOwens type showing the application of my invention thereto; Fig. 2 is asection through the machine taken on the line I][-][T of Figure 1,

theparts being drawn on a larger scale; Fig. 3 is a section similar toFig. 2 but taken on the line TTTI][I of Figure 1; Figs. 4, 5, 6, 7 and 8illustrate details of the invention hereinafter more fully to bedescribed.

1 have shown my invention applied to a rotary machine of the Owens typefor blowing hollow glass articles having a bottom. 1n the general typeof machine illustrated,

a portion of glass is gathered on the end of a blow-pipe and worked intoproper I shape, after which the blow pipe is inserted in a rotaryframework in the lower. part of which are molds for forming thechimneys. Air is supplied through-the blow pips and forms the glass intoan. article of the shape of the molds. My invention is designed to-remove the blow pipe together with the completed glass article afterthe formative operation just described has taken place, and

the blow pipes 14,'said pipes being releasably supported in the frames10 and 11 by means of spring jaws 15 and supportslG, respectlvelycarried on the frames 10 and 11. When in operative position the ends ofthe blow pipes 14 are adapted to project within the split molds 17 whichare mounted on a framework 18 carried on the lower portion of the shaft8, the said molds being opened and closed by the usual automaticmechanism 19. The carriage 9 and caps 13 are operated by the customarymechanism in machines of this type. The frame 10 is provided with fivecam pieces 10 which extend beyond the periphery of the frame and areadapted to engage the blow pipes while they are being taken out by thetake-out miphanism, as will hereinafter appear more The take-outmechanism for removing the blow pipes from the glass machine comprises ashaft 20 which is provided with splder frames 21 and 22 havingapproximately the same vertical position as the "frames 10 and 11 sothat the blow pipes will be engaged by the take-out mechanism sub-'stantially at their point of support in the glass machine. The shaft 20is rotatably mounted in a stem 23 (see particularly Figs. 1 and 5) which*is provided with external threads and is .carried in the bracket 24'se- .cured to the body of the glass machine. The

stem 23 is raised and lowered to any desired position by means of thehand wheel 25 bearing on the top of the bracket 24 and is locked in suchposition by means of the the said means comprising a hooked plate 28pivoted at 29 to the arms and held in the position indicated in Fig. 8by means of a spring 30. The inward movement of the plates is limited bythe abutments 31. The plates are curved so as to embrace the blow pipesand have their outer ends rounded at 32 in order to permit the blowpipes to slide into the hooks 27 against the pressure of the springs 30.

The spider 22 is shown in detail in Figs. 3, 4, 5 and 6. As thereillustrated, it comprises five arms, 22, which are pivoted at theirinner ends to a collar 33 keyed to the shaft 20 and have their outerends hooked at 34 to engage the blow pipes. Mounted on the stem 23immediately beneath the collar 33 is a collar 35 which carries a camportion 36 the surface of which is interrupted by five grooves 37. Eacharm 22 is provided with a downwardly depending projection 38 whichcarries a r0ller39 engaging the surface of the cam member 36, the partsbeing soarranged that the arms 22. are in a substantially horizontalposition when the rollers 39 lie in the grooves 37. When the spiderframe is rotated, it will readily be seen that the outer ends of thearms will be elevated slightly when the rollers ride out of the groovesonto the main surface of the cam member 36. The purpose of thisarrangement will hereinafter appear.

Referring to Figs. 3 and 7 it willbe seen that the supports 16 on thespider 11 comprise an adjustable plate-40 which is recessed to receivethe blow pipes and which is provided with three rollers 41 on which theblow pipes are supported by means of the collars 42 (see Fig. 1). Thespring-held jaws 15 and the supports 16 furnish a secure mounting forthe blow pipes but readily permit of their insertion and-removal.

' The blowpipes are provided with a second collar or abutment 43 spacedashort distance above the collars 42 and are engaged by the hooks of thearms 22' between the collars in such manner that the collars 43 supportthe blow pipes in the spider 22 against vertical displacement. Theplates 4 28 of the spider 21 support the blow pipes against lateraldisplacement with respect to the take-out mechanism. The operativepositions of the molds 17 are clearly indicated .in Fig. 2.

The operation of the mechanism thus far described is as follows: A blowpipe having a portion of molten glass gathered on its lower end-isplaced in the glass machine, the lower portion projecting into one ofthe molds. As the rotative movement of the glass machine continues, themold is closed and the article is blown, after which the mold opensautomatically aoa point adjacent the take-out mechanism, and shortlyslightly, lifting the blow-pipe upwardly thereby clearing the lower partof the glass article from the bottom of the mold. The cam 10 gives thetake-out frames sufficient impetus to carry them to the next groove onthe cam 36. The grooves thus serve a double function, namely, theyprovide for the desired vertical movement of the arms 22 and stop thetake-out mechanism at proper intervals giving it a step-by-step movementso that the parts are always in operative relation with respect to theglass machine. It will be apparent that the operation just describedwill be repeated for each mold on the machine. The blow pipes can bereadily removed from the take-out frames and the glass article struckofi in the usual manner.

From the foregoing it will be seen that the device is simple inconstruction, effective in operation, and eliminates a large portion ofmanual labor and increases the rapidity of the operation, thus greatlyreducing the cost of production. The operation is entirely automatic,and the liability of breakage is reduced to a minimum.

It will be noted that the molds are adapted to form a hollow glassarticle having a bottom. In removing articles from a glass machine ithas been found that the glass is frequently sufliciently hot to be in aplastic condition in which it will sag or lengthen out. In the type ofmachine shown the bottom of the glass article is hot and plastic andsags after the removal of the article from the machine. To overcome thisdefect I provide a pipe 46 leading from a fan 47 slve article issupported over the jet of air during the interval in which the take-outframe is stationary. The advantages of this arrangement will be apparentto those familiar with the art.

Having thus described" my invention and illustrated its use, what Iclaim as new and desire to secure by Letters Patent is the following:
